Cardiopulmonary resuscitation feedback improves the quality of chest compression provided by hospital health care professionals

High-quality chest compressions (CCs) are an important component of successful resuscitation. Suboptimal in-hospital CC are commonly reported. Skill degradation and fatigue have been implicated. We assessed the effect of a handheld feedback device on the measured and perceived quality of CC and rescuer physiologic response. This is a nonblinded randomized controlled study of nurses at an academic medical center. Participants performed CC on a mannequin either with or without a feedback device. Compression rate (CR) and compression depth (CD), heart rate, and oxygen saturation were documented. Perceived quality of CC, fatigue, and ease of use of the device were obtained. Twelve nurses were in the feedback group (FG) and 13 were controls. Mean CD was significantly higher in the FG (1.99 ± 0.37 in vs 1.52 ± 0.36 in; P = .005) and mean CR significantly lower in the FG (127 ± 13.8 per min vs 101 ± 9.7 per min; P ≤ .0001). Using a CD of more than 1.5 in and a CR of 90 to 100 as a composite measure of high-quality CC, the FG performed significantly better (81.4% ± 22.0% vs 10.4% ± 21.9%; P < .0001). Perceived CD, CR, and fatigue did not differ between groups; however, participants overestimated depth and underestimated rate. The FG ra...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

Head And Neck Squamous Cell Carcinoma

Squamous cell carcinomas account for >90% of all tumors in the head and neck region. Head and neck squamous cell carcinoma incidence has increased dramatically recently with little improvement in patient outcomes. Here is the latest research on this aggressive malignancy.

Signaling in Adult Neurogenesis

Neural stem cells play a critical role in the production of neuronal cells in neurogenesis is of great importance. Of interest is the role signalling mechanisms in adult neurogenesis. Discover the latest research on signalling in adult neurogenesis.

Bone Marrow Neoplasms are cancers that occur in the bone marrow. Discover the latest research on Bone Marrow Neoplasms here.

IGA Glomerulonephritis

IgA glomerulonephritis is a chronic form of glomerulonephritis characterized by deposits of predominantly Iimmunoglobin A in the mesangial area. Discover the latest research on IgA glomerulonephritis here.

Cryogenic Electron Microscopy

Cryogenic electron microscopy (Cryo-EM) allows the determination of biological macromolecules and their assemblies at a near-atomic resolution. Here is the latest research.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
